Rheological Behavior of the Guanidio Polyelectrolytes
Rheological Behavior of the Guanidio Polyelectrolytes
摘要
Abstract
The rheological behavior of polyhexamethylene guanidine hydrochloride (PHGC) and polyethylene guanidine stearate (PHGS) has been investigated using the capillary rheometer. It is shown that the polyelectrolyte melts are non-Newtonian of shear. thinning fluid. The melt viscosity, the flow activation energy and the flow temperature are high even if the molecular weight is not high. The melting viscosity of PHGC is higher than that of PHGS at the same experimental conditions. By comparison with the case of PHGS the non-Newtonian index of PHGC is smaller, the flow activation energy and the flow temperature of PHGC are higher, which was caused by the difference in their molecular structure.关键词
